Several factors occurred to bring about the eventual stock market crash
1928-29
In 1928
1. The central Federal Reserve Bankincreasedinterest rates on borrowedmoney
2. The central Federal Reserve Bankcut the money supply to the country as a whole
Thosewho had borrowedmoney to buyshares had to paymoreinterest on those loans and thereforebecamereluctant to borrow and invest
The head of the Federal Reserve Bankfell seriously ill, and the bank was thereforeunable to providestrong leadership when a crisisstruck
The Federal Reserve Bank had limitedpowers to manage the crisis
There was a growing awareness that depression was setting into the United States
This led to a loss of confidence in the markets and fewer people were prepared to invest their money in industry
Large numbers of banks, insurancecompanies and businesses became heavilyinvolved in speculating on the stock market to make a largeamount of money in a short time for their managers and shareholders
None of these institutions were effectivelycontrolled, and the Federal Reserve Bank had only limited regulatory powers
Banks were speculating on the stock market with money their customers had deposited as savings
Most US banks were small and served only their local communities, had few reserves and were deeply involved in the speculation that led to the Great Crash when they collapsed
If the banklost the money through unwise speculation, then it would simply go out of business and customers would lose all their money
Confidencecollapsed on Wall Street and sharesdropped in value by as much as 40% in a single day
October 1929
There had been a suddenfall in stock prices, but the marketrecoveredquickly
Late September
Over6 million shares were traded and $4 billion was suddenly wiped off the value of stocks
23 October
13 millionshares were sold and $9 billionlost
24 October ('Black Friday')
Over16 millionshares were sold, and overone-third of the value of all shares had dropped in a month
29 October
Thousands of individuals were ruined, and manysmallbanks and insurancecompanies went bankrupt
The customers who had trusted the banks with their savings just lost all their money
The stock marketrecoveredslowly over the next two years
Some argued that what happened was necessary to endunwise speculation by banks and businesses
It was a severe blow to confidence and didn't encouragenewinvestment
Less than 3% of US citizensownedstocks and shares themselves, but manyhundreds of thousands lost their life savings when the banks and insurancecompanies that had been speculating with their moneycollapsed
As a result of the stock market collapse
What had been a slowlydevelopingeconomicdecline then accelerated into a majoreconomic and social catastrophe
